3-((-3*7)/1)

(3-(-3*7))/1

3-(-3*(7/1))

3-((-3*7)*1)

(3-(-3*7))*1

3-(-3*(7*1))

3-(-3/(1/7))

3-((-3/1)*7)

3-((-3*1)*7)

3-(-3*(1*7))

3-((7*-3)/1)

(3-(7*-3))/1

3-(7*(-3/1))

3-((7*-3)*1)

(3-(7*-3))*1

3-(7*(-3*1))

((3*7)--3)/1

(3*7)-(-3/1)

((3*7)--3)*1

(3*7)-(-3*1)

3-(7/(1/-3))

3-((7/1)*-3)

3-((7*1)*-3)

3-(7*(1*-3))

(3*7)-(1*-3)

((3*7)/1)--3

(3*(7/1))--3

((3*7)*1)--3

(3*(7*1))--3

3-((1*-3)*7)

(3*1)-(7*-3)

((3*1)*7)--3

(3*(1*7))--3

((1*7)*3)--3

1*((7*3)--3)

(1*(7*3))--3

1*(3-(-3*7))

(1*3)-(-3*7)

1*(3-(7*-3))

(1*3)-(7*-3)

((1*3)*7)--3

1*((3*7)--3)

(1*(3*7))--3

第二个

((-9*6)/-2)-3

(-9*(6/-2))-3

(-9-(6-3))*-2

((-9-6)+3)*-2

(-9/(-2/6))-3

((-9/-2)*6)-3

-9*((-2-6)/3)

(-9*(-2-6))/3

((-9+3)-6)*-2

(-9+(3-6))*-2

-9/(3/(-2-6))

(-9/3)*(-2-6)

((6*-9)/-2)-3

(6*(-9/-2))-3

(6/-2)-(-9*3)

(6/(-2/-9))-3

((6/-2)*-9)-3

6*((-2--9)-3)

6*(-2-(-9+3))

(6/-2)-(3*-9)

6*((-2-3)--9)

6*(-2-(3+-9))

-2*(-9-(6-3))

-2*((-9-6)+3)

((-2--9)-3)*6

(-2-(-9+3))*6

-2*((-9+3)-6)

-2*(-9+(3-6))

((-2-6)*-9)/3

(-2-6)*(-9/3)

(-2-6)/(3/-9)

((-2-6)/3)*-9

((-2-3)--9)*6

(-2-(3+-9))*6

-2*((3+-9)-6)

-2*(3+(-9-6))

-2*(3-(6--9))

-2*((3-6)+-9)

(3--9)-(6*-2)

3-(-9+(6*-2))

((3+-9)-6)*-2

(3+(-9-6))*-2

(3--9)-(-2*6)

3-(-9+(-2*6))

(3-(6--9))*-2

((3-6)+-9)*-2

(3-(6*-2))--9

3-((6*-2)+-9)

(3-(-2*6))--9

3-((-2*6)+-9)
